We were all taught how to cross a street: Look both ways. But, in some cities, you'll also have to ask permission by pressing a tiny button and waiting your turn. Those little buttons on walk signals have been nicknamed "beg buttons"—because walkers are pretty much begging to be able to cross.

Here in Los Angeles, if you don't press them, you won't even get the opportunity to cross—the light will turn red, stopping the opposing traffic, but you'll never get a walk signal and the light won't stay green long enough for you to actually make it to the other side.

It's annoying for walkers: have you ever tried to walk a few blocks, stopping to hit the button at every single intersection? Or hit the button just a few seconds too late and had to wait a whole additional cycle? But it also illustrates the backwardness of our street design: pedestrians, who are supposed to have the right-of-way, are required to press a button at an intersection in order to get a walk signal, which should happen automatically. This video illustrates the problem well:

This struggle is nothing new, of course. The term "jaywalking" was invented by the auto industry to shame pedestrians in the 1920s. But it has become an issue again due to recent, highly publicized crackdowns on jaywalking in Los Angeles and New York City. As reported a few weeks ago, offenders are being issued tickets upwards of $200. (That's actually not all that bad compared to some other places: In Singapore you could go to jail for three months.)

But the problem, especially in L.A., is that jaywalking is not only defined as running across the street mid-block without a signal—you can also get a ticket for stepping off the curb at a signal after the "countdown" starts.

This is not to say that people don't cross the street illegally—they definitely do. And who hasn't tried to beat the clock by running across the street before that countdown runs out? The problem with beg buttons is that they criminalize walkers—they provide a very specific way for police to blame pedestrians for an uptick in collisions.

"We're heavily enforcing pedestrian violations because they're impeding traffic and causing too many accidents and deaths," LAPD officer Lydia Leos told the LA Downtown News. (This was just a week before an LAPD officer struck a pedestrian in a crosswalk—with L.A. Mayor Eric Garcetti in the back seat.)

According to law enforcement, jaywalking crackdowns and beg buttons are required because pedestrians are making the streets unsafe. Wait, pedestrians are dangerous? These sentiments are echoed in a recent New York Times article by Tom Vanderbilt, who eloquently explains the ridiculousness of this logic:

Those humans in Los Angeles who began walking a second or two after the light was blinking were, after all, violating the "Vehicle Code." Note that cars, apparently, do not violate a "Human Code."

As for pedestrian safety, which is the typical stated purpose of jaywalking crackdowns, more pedestrians generally are killed in urban areas by cars violating their right of way than are rogue pedestrians violating vehicles' right of way. Then there are those people struck on sidewalks, even inside restaurants. What do we call that? Jay-living?

There are some solutions which can help turn this misguided attitude around. In D.C., for example, instead of cracking down on deviant pedestrians, cameras have been installed at intersections specifically to catch drivers who "block intersections, roll through stop signs, fail to yield to pedestrians, pass through an intersection at an unsafe speed or take an oversize bus or truck on a street too small to accommodate it."

The fines for blocking an intersection or rolling through a stop sign are $50—still far lower than the jaywalking ticket you might get in other cities. But it's a step in the right direction: Law enforcement is targeting the entity that's most likely to do the most harm.

Another option is to give the pedestrian a few extra seconds to cross, what planners call a "leading pedestrian interval" or LPI. Here, walk signals give pedestrians a five second head start before the cars crossing with them get the green light. This not only gives extra time to cross the street—especially important for wide streets and elderly residents or people with wheelchairs or strollers—it allows the pedestrians to get out into the streets and be more visible before the cars start driving through, preventing collisions from right turns.

This solution is great: it doesn't require any additional infrastructure, just a reprogramming of the signal's schedule.

We should also look at redesigning the intersections themselves. There has been a resurgence in the crosswalks called pedestrian scrambles which stop all vehicular traffic (even right turns) and allow walkers to cross in all directions, including diagonally, which is the safest and most effective way to get pedestrians across the street. If you look at the intersection above, which is Oxford Circus in London, you'll see that not only do the signals stop all traffic, but the pedestrian paths themselves are highlighted with paint and reflectors. This clearly delineates the path that's for walkers and makes them feel better about crossing. It redesigns the intersection for pedestrians, as it should be.

Scrambles aren't the only way to make walkers safer, and many of the best solutions draw from a variety of improvements. In New York City last night, the DOT revealed a comprehensive pedestrian safety redesign for a deadly intersection on the Upper West Side that included a shorter wait for pedestrians, limited left turns, and a redesigned crosswalk.

Designing more visible crosswalks is a pretty simple thing to do, but most cities likely won't embark upon massive pedestrian signaling improvements until there's a particular density of walkers to use them. The reason beg buttons have been phased out in cities like New York is because there's a high number of walkers at pretty much any intersection. If another city made an announcement to remove their beg buttons, I have a feeling we'd hear from frustrated drivers who would complain that their time stopped at a light will be longer because they'll have to wait, even when no pedestrians are present.

There are other technologies that can help circumvent this problem, like sensors that will activate a walk signal without having to press a button, but that still enforces the divide between car vs. pedestrian—and it will cost cities more money to install.

Of course, this is not an option for very, very busy intersections, but you've likely experienced why this is a better solution for yourself while crossing smaller streets. A stop sign allows the driver and walker to make eye contact and engage in a dialogue of sorts, agreeing to keep each other safe. And that's exactly what we should be doing: making everyone on the street feel safe and acknowledged.

Once we get rid of the beg buttons, we can redesign those interactions to be better experiences for walkers. At one intersection in Germany, as part of a project by Sandro Engle, Amelie Künzler, Holger Michel, and a team of students, the beg button becomes a gaming interface where you can play a modified version of Pong with someone across the street:

While I'm not sure that the signal in this instance is making anyone safer, it does create awareness, and makes waiting to cross the street a lot less tedious and a lot more fun. [New York Times]
